如何使用jQuery的getJSON()方法传递请求标头?

问题描述：

我需要执行getJSON()请求，但是如何传递授权和自定义标头?

I need to do a getJSON() request, but how do I pass authorisation and custom headers?

我遇到的问题是请求标头使用名称，而不是值.通过提琴手的手动请求显示该URL，然后将其作为选项而不是GET/Url插入.

I am getting issues that the request header is taking the name, but NOT the values. The URL is being shown through a manual request in fiddler to being inserted in as options instead of GET/Url.

这是我们尝试做的一个例子，在提琴手中效果很好；如何使用AJAX函数复制它?

Here is an example of what we are trying to do that works fine in fiddler; how can I replicate this with the AJAX function?

GET /Service.svc/logins/gdd53535342/houses/vxcbdfsdg/people/dsgsdggd?format=json HTTP/1.1
User-Agent: Fiddler
Authorization: Basic rgbg423535fa23y4436
X-PartnerKey: df3fgeg-g5g6-b55b-f3d2-dsgg353523
Host: 154.34.53.54:2757

JavaScript代码:

JavaScript code:

xhr = new XMLHttpRequest();

$(document).ready(function() {
  $.ajax({
    url: 'http://localhost:437/service.svc/logins/jeffrey/house/fas6347/devices?format=json',
    type: 'GET',
    datatype: 'json',
    success: function() { alert("Success"); },
    error: function() { alert('Failed!'); },
    beforeSend: setHeader       
  });   
});

function setHeader(xhr) {
  xhr.setRequestHeader('Authorization', 'Basic faskd52352rwfsdfs');
  xhr.setRequestHeader('X-PartnerKey', '3252352-sdgds-sdgd-dsgs-sgs332fs3f');
}

提琴手正常请求标头:

GET /service.svc/logins/jeffrey/house/fas6347/devices?format=json HTTP/1.1
User-Agent: Fiddler
Authorization: Basic faskd52352rwfsdfs
X-PartnerKey: 3252352-sdgds-sdgd-dsgs-sgs332fs3f
Host: localhost:437

在Ajax()请求标头中显示提琴手:

Fiddler Through Ajax() Request Headers:

我同意sunetos的观点，您必须使用$ .ajax函数才能传递请求标头.为此，您必须为beforeSend事件处理程序编写一个函数，该函数是$ .ajax()选项之一.这是有关如何执行此操作的快速示例:

I agree with sunetos that you'll have to use the $.ajax function in order to pass request headers. In order to do that, you'll have to write a function for the beforeSend event handler, which is one of the $.ajax() options. Here's a quick sample on how to do that:

<html>
  <head>
    <script src="http://code.jquery.com/jquery-1.4.2.min.js"></script>
    <script type="text/javascript">
      $(document).ready(function() {
        $.ajax({
          url: 'service.svc/Request',
          type: 'GET',
          dataType: 'json',
          success: function() { alert('hello!'); },
          error: function() { alert('boo!'); },
          beforeSend: setHeader
        });
      });

      function setHeader(xhr) {
        xhr.setRequestHeader('securityCode', 'Foo');
        xhr.setRequestHeader('passkey', 'Bar');
      }
    </script>
  </head>
  <body>
    <h1>Some Text</h1>
  </body>
</html>

如果您运行上面的代码并使用Fiddler之类的工具查看流量，则会看到传入了两个请求标头:

If you run the code above and watch the traffic in a tool like Fiddler, you'll see two requests headers passed in:

值为Foo的安全代码
值为Bar的密码

setHeader函数也可以在$ .ajax选项中内联，但我想将其标出.

The setHeader function could also be inline in the $.ajax options, but I wanted to call it out.

希望这会有所帮助！
